DEVICE FOR FILLING FOUNTAIN-PENS.

SPECIFICATION forming part of Letters Patent No. 784,982, dated March 14, 1905.

Application filed June 7, 1904. Serial No. 211.469.

T0 (bl/1 1071,0777, it nan/y concern.-

Be it known that I, GEORGE N. BYL, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Device for Filling Fountain-Pens, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a device whereby fountain-pens may be directly filled from a vessel in which ink is contained, the rapidity of the feed being under the absolute control of the operator.

Another purpose of the invention is to provide a flexible suction top or cap for the inkcontaining vessel, which top or cap carries a conducting-tube, the said top or cap being capable of ready removal and application.

Another purpose of the invention is to provide a reinforcing-spring for the top or cap which will tend to extend the lifetime of the said top or cap and prevent the top or cap from being accidentally forced suddenly downward and the pen-barrel consequently overflowed while being filled, and, further, to provide a stable support for the conducting-tube and a simple and efleotive means of holding such support in position in the cap or cover.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a vertical section taken at about the center of the device; and Fig. 2 is a similar section, illustrating a slightly-modified form of the device.

A represents a vessel adapted to be filled with ink, which vessel is provided with a neck 10, and at the upper portion of the neck an outwardly-extending flange 11 is formed.

cated, or a sustaining material of any other character may be employed as a substitute for the cork.

A spring-cap 15 is employed in engagement with the outer face of the extension 13 of the diaphragm B, engaging with the body of the said diaphragm, as is shown in Fig. 1, and the said cap 15 is provided with a central opening, as is likewise the cork 14. A conducting-pipe 16 is passed through the said openings in the cap and in the cork down into the receptacle A, which conducting-tube 16 is provided above the cap 15 with a downwardly-inclined member 16, adapted to conduct the ink into the barrel of a pen.

The diaphragm B at its base portion is so constructed as to fit over the flange 11 of the neck 10 of the receptacle A and to extend un der the said flange, as is shown in Fig.1. Further, the diaphragm is held in position on the neck of the receptacle A by means of a clamping-ring 12, which may be of rubber, steel, brass, or any material, and the upper portion of the clamping-ring 12 is curved inwardly, so as to extend over that portion of the diaphragm which is at the upper portion of the flange 11 on the neck of the receptacle.

In operation by pressing the diaphragm B downward the liquid contained in the receptacle A is forced up through the tube 16 and out through the delivery-section 16 of the tube, and the flow of ink or liquid from the receptacle A will be guided by the extent and the rapidity with which the diaphragm B is pressed downward.

It is obvious that when a filling device of the character described is thus constructed the barrel of a fountain-pen may be quickly filled with ink and in a cleanly manner.

In order that the diaphragm B shall not readily perish under frequent use and in order that its elasticity may be maintained, I place a spring 17, preferably a conical spring, within the diaphragm B, which spring at its upper end engages with the cork l4 and at its lower end has bearing upon the mouth or neck of the receptacle A.

In Fig. 2 I have illustrated a slight departure in the construction of the device, inasmuch as the diaphragm therein indicated as 18 is a flat diaphragm fitted over the neck of the receptacle in the same manner as described in Fig. l and is provided with an upwardlyextending neck-section 19, in which a cork 20 is located, held in place by a cap 22, corresponding to the cap 15, (shown in Fig. 1,) and the conducting-tube 21 is passed through this neck-section of the diaphragm and through the said cork into the vessel which the device therein shown is adapted to cover. This construction affords a simple means of manufacturing the article and operates in the same manner as does the construction illustrated in Fig. l.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. A device for filling fountain-pens, consisting of a receptacle provided with a flanged neck, an ejecting-cover of a flexible material located over the flanged portion of the neck, a clamping-ring for the said ejecting-cover, located at the flanged portion of the neck of the receptacle, and a stable support located in the upper portion of the ejecting-cover, and a conducting-tube extending down through the said cover and the stable support into the said receptacle, which conducting-tube is provided with an upper delivery branch.

2. In a device for filling fountainpens, a receptacle provided with a neck and a flange on the neck, an elastic diaphragm secured to the said flanged portion of said neck, a clampingring holding the said diaphragm in such engagement, the diaphragm being provided With an upward extension, a stopper located in the said extension of the diaphragm, a clamp engaging with the outer i'ace of the said extension of the diaphragm, and a conducting-tube passed down through the said extension of the diaphragm, the clamp located at such point and the stopper, which conducting-tube extends down into the receptacle and is provided with a delivery branch above the extension of the diaphragm, as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE N. BYL.
